I have 1/2" poly tubing connected to my gh water supply with a filter and 25lb pressure reducer, and have a line running down both sides of the gh near the ceiling. I just got through trying a 1/2gph fogger nozzle on each line, but it still gets the plants too wet. I've thought of trying a 10 micron fogger nozzle, but I haven't found a company which says 'here it is, this is what it costs'. I think I could hook up a regular water timer to cut on and off at certain times, but it would be much bettr to have a humistat so it could be controlled automatically. Two places I checked want over $1,000 for an automated system. I'll hang the orchids under the big oak tree and spray 'em with the garden hose before I spend that kind of money!
